PVC vs. UPVC, what is the difference?

     PVC (polyvinyl chloride) and UPVC (unplasticized polyvinyl chloride) are two types of vinyl. 

   They are widely used in the construction industry due to their versatility and flexibility to produce various shapes.

   However, they serve different functions. PVC is often used to make siding and fences, whereas UPVC is used for window and door construction. PVC is not suitable for window and door construction due to its chemical composition.

Properties of PVC

    PVC is banned in Europe and in all toy products in the United States due to its toxic properties. PVC contains phthalates and BPA, which are chemical compounds used to plasticize vinyl and to give it its renowned flexibility.  As a result, PVC is more porous and requires more maintenance over time to remove surface stains. Therefore, PVC is not often used in window and door construction.

    Phthalates and BPA cause harmful effects to the environment and to our health, especially in the event of a fire when the chemicals become airborne. When exposed to high temperatures, PVC emits toxic fumes that can cause damage to several organ systems. PVC is still widely used in North America, as there are fewer environmental standards and restrictions in place compared to Europe.

Properties of UPVC

    UPVC refers to unplasticized polyvinyl chloride. As the name suggests, it does not contain phthalates or BPA, rendering a safe product for the environment while still maintaining the benefits of a vinyl window frame. UPVC is a robust material, especially used in window construction due to its thermal efficiency and durability.

• UPVC offers several additional benefits:
• Less porous surface significantly reduces maintenance
• High energy efficiency
• Increased lifespan to last decades
• Rigid and does not flex
• High impact resistance
• Bright white frame and will maintain its colour over time
• Recyclable material
